That is an interesting idea, never heard that one before, but it makes some sense.
But here's a question,
If a motor is stuck from rusted cylinders and rings and you break it free, aren't you then taking all that rust and scoring the cylinders to the point of being an oil burner?
I guess that confuses me, I hear the stories on the ones that sat in the field, they free them up and they run, but it seems like all the moisture..rust would tear everything up.
Or do you break them free to help you tear them apart? Can they still be usable after being freed?
What do you think of the idea of using air pressure?
I read to avoid anything or force that might bend the rods, but it seems there isn't much of a choice.
I think mine was already stuck when they put the head back on. It's either a bad head that leaked and rusted or however long it sat without the head before he put it on. He said there was some rust, but no idea how bad it was. I'm thinking real bad.
